Substituted tryptamines

For the eponymous compound, see Tryptamine.

Substitutive structure of a tryptamine molecule

Substituted tryptamines (also referred to as tryptamines) are a group of organic compounds that are based upon the tryptamine structure. The class is composed of all the derivative compounds which can be formed by substituting one or more hydrogen atoms in the tryptamine core structure with other substituents. Natural tryptamines were found in most plants and animals, they originate from the decarboxylation of tryptophan.

The chemical class inculdes hormons like melatonin and neurotransmitters like serotonin. Pharmacologically, many substituted tryptamines are known for being able to produce psychedelic and entheogenic effects. Prominent examples include DMT, psilocybin, and ibogaine.

An investigation of dozens of psychoactive tryptamine compounds was published by Ann and Alexander Shulgin under the name TiHKAL in 1997.

Chemistry

The structure of any substituted tryptamine is comprised of an indole ring with attached amino group via a two-carbon sidechain (monoamine chain) at R₃. Ring unsubstituted tryptamines or so called "base tryptamins" can have various substitutions at the nitrogen (R_N1 and R_N2) and at R_α. Ring substituted tryptamines can furthermore be substituted at the R₄ and R₅ positions at the indole ring.
